A lot of people don't take Adderall every day. My Pdoc is totally fine with me taking it "as needed" as long as I never take more than the prescribed amount.

Good news is, once I finished school, I found I needed the Adderall much less often. Instead of having to sit in a classroom and listen, I get to actually DO things, and often they are interesting, useful things. All jobs have some tedious parts, but there may be fewer tedious parts at work than at school.
